ローター (Fabricated Copper Rotors)
Wieland manufactures rotors in copper and aluminum for highly efficient induction motors. This enables you to meet the increasing need for energy efficiency and economy without the need for rare earth minerals. We also offer engineering support during the development of your application-specific design. Furthermore, Wieland offers two different processes to produce rotors to meet your individual requirements. Both processes offer manufacturing with a very high degree of material filling without air inclusions, and we can draw on a wide range of experience from prototypes to series production.
特長
The fabricated Wieland copper rotor is a new and innovative design, which is designed according to your requirements. Due to the disc-shaped design of the short-circuit ring, different materials can be combined individually, and fulfill the requirements for higher power densities and rotation speeds. Additionally, the fabricated design has a higher mechanical strength and enables a very scalable, flexible, and economical approach for rotor production.
